Struct gtk4::IconView

source ·
#[repr(transparent)]
pub struct IconView { /* private fields */ }
Expand description

IconView is a widget which displays data in a grid of icons.

IconView provides an alternative view on a TreeModel. It displays the model as a grid of icons with labels. Like TreeView, it allows to select one or multiple items (depending on the selection mode, see set_selection_mode()). In addition to selection with the arrow keys, IconView supports rubberband selection, which is controlled by dragging the pointer.

Note that if the tree model is backed by an actual tree store (as opposed to a flat list where the mapping to icons is obvious), IconView will only display the first level of the tree and ignore the tree’s branches.

CSS nodes

iconview.view
╰── [rubberband]

IconView has a single CSS node with name iconview and style class .view. For rubberband selection, a subnode with name rubberband is used.

pub fn tooltip_context( &self, x: i32, y: i32, keyboard_tip: bool ) -> Option<(TreeModel, TreePath, TreeIter)>

This function is supposed to be used in a GtkWidget::query-tooltip signal handler for IconView. The @x, @y and @keyboard_tip values which are received in the signal handler, should be passed to this function without modification.

The return value indicates whether there is an icon view item at the given coordinates (true) or not (false) for mouse tooltips. For keyboard tooltips the item returned will be the cursor item. When true, then any of @model, @path and @iter which have been provided will be set to point to that row and the corresponding model.

x

the x coordinate (relative to widget coordinates)

y

the y coordinate (relative to widget coordinates)

keyboard_tip

whether this is a keyboard tooltip or not

Returns

whether or not the given tooltip context points to an item

pub fn item_activated(&self, path: &TreePath)

Activates the item determined by @path.

path

source

pub fn path_is_selected(&self, path: &TreePath) -> bool

Returns true if the icon pointed to by @path is currently selected. If @path does not point to a valid location, false is returned.

path

A TreePath to check selection on.

Returns

true if @path is selected.

source

pub fn scroll_to_path( &self, path: &TreePath, use_align: bool, row_align: f32, col_align: f32 )

Moves the alignments of @self to the position specified by @path. @row_align determines where the row is placed, and @col_align determines where @column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

If @use_align is false, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the item onto the screen. This means that the item will be scrolled to the edge closest to its current position. If the item is currently visible on the screen, nothing is done.

This function only works if the model is set, and @path is a valid row on the model. If the model changes before the @self is realized, the centered path will be modified to reflect this change.

path

The path of the item to move to.

use_align

row_align

The vertical alignment of the item specified by @path.

col_align

source

single

true to emit item-activated on a single click

source

pub fn set_column_spacing(&self, column_spacing: i32)

Sets the ::column-spacing property which specifies the space which is inserted between the columns of the icon view.

column_spacing

the column spacing

source

pub fn set_columns(&self, columns: i32)

Sets the ::columns property which determines in how many columns the icons are arranged. If @columns is -1, the number of columns will be chosen automatically to fill the available area.

columns

the number of columns

source

pub fn set_cursor( &self, path: &TreePath, cell: Option<&impl IsA<CellRenderer>>, start_editing: bool )

Sets the current keyboard focus to be at @path, and selects it. This is useful when you want to focus the user’s attention on a particular item. If @cell is not None, then focus is given to the cell specified by it. Additionally, if @start_editing is true, then editing should be started in the specified cell.

This function is often followed by gtk_widget_grab_focus (icon_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

source

pub fn set_item_width(&self, item_width: i32)

item_width

the width for each item

source

pub fn set_margin(&self, margin: i32)

pub fn set_markup_column(&self, column: i32)

source

pub fn set_reorderable(&self, reorderable: bool)

This function is a convenience function to allow you to reorder models that support the GtkTreeDragSourceIface and the GtkTreeDragDestIface. Both TreeStore and ListStore support these. If @reorderable is true, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s row_inserted and row_deleted signals. The reordering is implemented by setting up the icon view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

This function does not give you any degree of control over the order – any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

reorderable

true, if the list of items can be reordered.

source

pub fn set_row_spacing(&self, row_spacing: i32)

Sets the ::row-spacing property which specifies the space which is inserted between the rows of the icon view.

source

pub fn set_text_column(&self, column: i32)

Sets the column with text for @self to be @column. The text column must be of type G_TYPE_STRING.

column

A column in the currently used model, or -1 to display no text

source

pub fn set_tooltip_cell( &self, tooltip: &Tooltip, path: &TreePath, cell: Option<&impl IsA<CellRenderer>> )

Sets the tip area of @tooltip to the area which @cell occupies in the item pointed to by @path. See also gtk_tooltip_set_tip_area().

See also gtk_icon_view_set_tooltip_column() for a simpler alternative.

tooltip

a Tooltip

path

a TreePath

cell

a CellRenderer

source

pub fn set_tooltip_column(&self, column: i32)

If you only plan to have simple (text-only) tooltips on full items, you can use this function to have IconView handle these automatically for you. @column should be set to the column in @self’s model containing the tooltip texts, or -1 to disable this feature.

When enabled, GtkWidget:has-tooltip will be set to true and @self will connect a GtkWidget::query-tooltip signal handler.

Note that the signal handler sets the text with gtk_tooltip_set_markup(), so &, <, etc have to be escaped in the text.

column

an integer, which is a valid column number for @self’s model

source

pub fn set_tooltip_item(&self, tooltip: &Tooltip, path: &TreePath)

Sets the tip area of @tooltip to be the area covered by the item at @path. See also gtk_icon_view_set_tooltip_column() for a simpler alternative. See also gtk_tooltip_set_tip_area().

If no area is specified when creating the icon view with gtk_icon_view_new_with_area() a CellAreaBox will be used.
